Quantifying the risk of groundwater contamination from hydraulic fracturing in coal seam gas operations in Australia.

煤层气开采对地下水资源的影响引起了社会各界的热议。本项目将评估煤层气开采中水力压裂对地下水污染的风险。至关重要的是，煤层中天然存在的化合物和注入的化合物不会被动员到由水孔顶部的含水层中。该项目将建立煤层气水力压裂过程的精确、具体、动态数值模型。这将有助于预测特定煤层中受刺激裂缝的最大垂直范围，并有助于建立标准，以确定煤层气井在何时何地进行压裂是安全的，而不是地下水污染。

Concern for impacts to groundwater resources due to coal seam gas operations has led to heated debate in the community. This project will assess the risk to groundwater contamination from fracking in coal seam gas operations. It is critical that naturally occurring compounds in the coal seam and injected compounds are not mobilised to aquifers topped by water bores. This project will build accurate, site-specific, dynamic numerical models of the hydraulic-fracturing process in coal seam gas operations. This will enable prediction of the maximum vertical extent of stimulated fractures in specific coal seams and will help establish criteria for when and where fracking in coal seam gas wells is safe in relation to groundwater contamination.
